Drag a $100 bill through MSNBC and there's no telling what you'll find. On today's Morning Joe, the ever-classy James Carville likened GOP primary voters to low-quality prison inmates.

Carville made his asinine analogy in responding to Joe Scarborough's suggestion that Republicans can still prevail in coming election cycles if they do the "smart thing." Carville said the situation reminded him of what Lester Maddox said the problem was in the Georgia prison system: the quality of the inmates. According to Carville, the GOP's problem is the quality of Republican primary voters. View the video after the jump.

Carville's slur prompted Scarborough to say he was leaving to get a cup of coffee, putting Mika in charge of the "Young Marxist Variety Hour," a reference to the all-liberal panel composed of Carville, David Axelrod, Eugene Robinson, John Heilemann and Walter Isaacson.

JOE SCARBOROUGH: At this stage of the cycle, if Republicans actually wise up, smarten up, and I've got a lot of evidence suggesting that they are, that they're tired of losing. They've lost five out of six of the last presidential campaign popular votes, that they could turn things around. But, James Carville, they've got to do the right thing here. They've got to do the smart thing here.

JAMES CARVILLE: Joe, the problem is what I call the Lester Maddox problem. [Former Georgia governor] Lester Maddox famously said the problem with the Georgia prisons is the quality of the inmate. The problem with the Republican party is the quality of the person who votes in primaries. 59% of them say the party is not conservative enough.

SCARBOROUGH: Mika, I think I'm just going to go get a cup of coffee and leave this Young Marxist Variety Hour to you.
